Kardashian reportedly sent invitations to A-listers including Fergie and Beyonce. Except these weren't just invitations. They were full-blown music boxes.

And not just any music boxes -- music boxes that played a lullaby version of West's 'Hey Mama.'

Kardashian's sisters Khloe and Kourtney, mom Kris Jenner and family friend (and wife of West's former manager) Shelli Azoff are throwing the "garden chic" brunch on June 2.

A source told Us Weekly that Kardashian is more than ready for the birth after seeing her sister Kourtney pop out two babies of her own. "Kim is not scared at all and has no fears," the insider said, adding that the reality startlet and West will stay stateside before going on West's tour with their spawn. "This was always the plan."

And if you're wondering whether the theme will be pink or blue, the ballerina enclosed in the music box looks like a smaller version of Kardashian. And uh, it's a ballerina.
